What's inside

Everything between a datasheet and a working build.

Four ways into the same body of knowledge — pick whichever matches how you learn.

Documentation

Board references, pinouts, and library docs for 15 platforms — from Arduino to BeagleBone Black.

Firmware programming

C, C++, Embedded C, MicroPython, Assembly and the tooling around them — Git included.

Tutorials & projects

Step-by-step builds and community projects, searchable by board and difficulty.

Community

Ask the question you can't find in a datasheet. Answered by people who've debugged it.

Browse by board

Start from the hardware you already have.

Arduino

Uno, Nano, Mega and the whole AVR-based family.

Getting started

Raspberry Pi

Full Linux SBCs for projects that need more than a microcontroller.

Getting started

STM32

ARM Cortex-M boards for when timing and performance matter.

Getting started

ESP32
